To evaluate the use of protospecies in the breeding of cultivated sugarcane, we examined 50 protospecies for ratoon character variation. Ratoon germination rate varied between 7% and 184%, and the ratio of productive tiller between 0 and 360%. The best materials in regard to effective stem, plant height, stem diameter, brix and sucrose were Guangze bamboo cane, Sichuan reed cane, badila, Deyang large leaves and 28NG251. Two good traits were exhibited by 21 protospecies, three good traits by 11 protospecies, and four good traits by 14NG124. Infection rate of S.sinense R by mosaic disease and smut was higher than in S.officinarum L. and S.barberi J. It was noted that Deyang big leaves, Guangxi bamboo cane and Wenshan cane were also infected by mosaic disease and smut.
